SOUND-INSULATING DEVICE FOR 13UILDIN G CONSTRUCTIONS.

To all whom it may concern:

Be-it known that I, HARRY B. WHEELER, a

citizen of the United States, residing at Chlcago, in the county of Cook and State of Illinois, have invented a certain new and useful Improvement in Sound-Insulating I Devices for Building Constructions,

a which the following is a full, clear, concise,

and exact description, reference being had to the accompany ng drawings, forming a part of this specification.

My inventionrelates to improvements 1n sound insulating devices for floor and wall constructions for buildings and has for'its object the provision of improved means for insulating the floor or wall to provlde a sound proof construction so that the sounds on one floor of the building will not be trans.- mitted to the floor above or below, and so that the sounds in one room will not be transmitted to the adjacent rooms.

With these objects 'in view I provlde a metallic plate arranged to be secured to the rough flooring in floor-constructions and to studding in wall constructlons. 'Thls metallic plate is bent at its outer end so as to extend around the upper surfaceof'a nailingstrip to hold the nailing strip agalnst movement away from the studding or rough flooring. To insulate the nailing strip from the metallic plate I interpose between the tion with the accompanying drawings wherein Figure 1 is a cross sectional view of the preferred form of my invention showmg 1t applied to floor constructions;

Fig. 10 is a'perspective view of a nailing strip and two holders or retaining devices as shown in Fig. 1 holding the strip in place.

is attached by means of the nails 1212, or any other suitable means, the holder or clamping device 13. In the preferred form of my lnventionthis clamping device conslsts of two pieces 14 and15 riveted together.

as shown at 16, the member 15 constituting the base member which is attached to the support 11, as referred to. The member 14 normally extends upwardly, the dotted lines. The nailing strip is shown at 1-7 and is provided With a notch 18 having a beveled surface 19. A layer of insulating material, such as felt, is interposed between the clamping device and the nailing strip as illustrated at 20 and the lower end of the layer is clamped between the upturned end 21 of the base member 15 and is held in such position by means of the nails 1212 which extend through the insulating material;

After the clamping device has been secured as shown byto the rough flooring and the nailing strip,

together with the insulating layer 20, assembled, the upper end of the clamping device 13 is forced downwardly to the position illustrated in full lines. This is accomplished by means of a hammer or hatchet and serves to hold the nailing strip against movement away from the rough flooring or support 11. The flooring 22 is then nailed to the strip 17 as indicated. To insure against any possible connection between the clamping device and the flooring 22 the felt layer 20 may be extended at its upper end around the upper end of the clamping device to entirely separate the clamping device from the upper flooring. The clamping devices 13 are spaced approximately two feet apart and are positioned alternately on opposite sides of the nailing strip, as most clearly shown in Fig. 10.

In Fig. 3 the-clamping device 13 is constructed of one piece and has its underside stamped upwardly as shown at 23 so as to space the nailing strip away from the rough flooring or support 11*. In this construction the upwardly extending part of the clamp 13 is stamped out of the piece 24 which is nailed to the support.

Fig. 4 shows the clamping device applied to wall constructions and has its base plate 15 bent to form an inwardly projecting ranged to engage that side of the nailing piece 25 which is nailed, as shown, to the studding 26. The wall 27 is secured tothe nailing strip 17 as is the upper flooring shown in Fig. 1.

v Fig. 5 shows a floor constructionfsimilar to that of Fig. l except-that the member 1% includes an upwardly extending piece 28, ar-

strip opposite the clamping portion of the retainer.

Fig. 6 shows a floor construction wherein the nailing strips 17 are supplied with beveled surfaces 29 and 30 which extend the full length of the strip if desired. In this case the layer of felt 20 is inserted, as-

shown, and the upper portion 14 forced from the position shown in dotted lines to the position shown in full lines to hold the nailing strip in place. The several clamping devices are placed alternately on opposite sides of the nailing strip.

In Fig. 7 the clamping devices 14c are constructed with their upper ends 31 bent inwardly to extend over the beveled surface of the notch 18 formed in the nailing strip 17", thus avoiding the necessity of bending the clamping devices to the extent necessary in the other devices shown.

Fig. 8 shows a clamping device embedded in concrete. In this construction the clamping device consists of the two members 14 and 15 The member 15 constitutes the base member and is bent upon itself, as

indicated, to provide at its right hand end (Fig. 8) a clamp for holding the lowerend of the felt strip 20 The member 14* extendsthrough the slots 32 in the base 15 and has its lower endbent, as shown at 33, and provided with an aperture 34. to permit nailing ofthe piece 14? to the support 35. The member 14 is first nailed to the support 35 and the concrete poured around the member 14 After the concrete becomes hard the member 15 is placed over the clamp 14 and the felt layer 20 positioned between the right hand ends of the member 15 "The nailing strip 17 is then notched and placed in position whereupon the upper end of the clamping device 142 is hammered downwardly, as shown, to hold the nailing strip in place. Due to the enlarged end 33 of the member 14 the clamping device is securely anchored'in the concrete.

In Fi 9 the clamping device 36 takes the form 0 an angle andis attached by means of two nails 37 to the support 11 The felt layer 20 is placed between the clamp 36 and the nailing strip 17 h and between the nailing strip and the support 11 The nailing strip is notched, as shown, and the upper end of the clamp 36 hammered down from the' dotted iine position to ful line position to hold the strip in place. The several clamps 36 used on each nailing strip are placed alternately on opposite sides of the strip, as are the devices shown in Fig. 10 so that lateral displacement of the nailing strip is prevented.

It will be seen from the above description that I provide means for insulating the nailing strip from its support which is simple in construction and can easily and quickly be applied to the nailing strips. Due to the fact that the clamping device is bent by what ll claim as new and desire to secure by Letters Patent of the United States is: 1. In a building construction the provision of a support, a nailing strip, a malleable metal nailing strip holder secured to the support and extending over the nailing strip to prevent movement of the strip away from the support, and a layer of insulating material between the nailing strip and the holder to insulate the strip fromthe suport. p 2. In a building construction the provision of a support, a nailing strip provided with a notch in its side opposite the support, a malleable metal retaining device carried by the support and having an upwardly extending part fitting into said notch, and sound insulating material between the retainer and the nailing strip. 3. In a building construction the provision of a support, a nailing strip provided with a notch in one of its edges opposite the the nailing strip to prevent movement 'of the strip away from the support, said retainers being positioned'along the strip so that the outwardly extending pieces are alternately positioned on opposite sides ofthe nailing strip, and sound insulating means between the retainers and the nailing strips.

5. In a building construction the provision of a support, a nailing strip insulated from the support, a malleable metal nailing strip holder secured to the support and having its base interposed between the nailing strip and the support, said holder having a part extending outwardly from the support In witness whereof hereunto subscribe on one side of the nailing strip and over the my name this 18th day of December, A.
